Duality invariance of non-anticommutative N=1/2 supersymmetric U(1) gauge theory

A parent action is introduced to formulate (S-) dual of non-anticommutative N=1\2 supersymmetric U(1) gauge theory. Partition function for parent action in phase space is utilized to establish the equivalence of partition functions of the theories which this parent action produces. Thus, duality invariance of non-anticommutative N=1\2 supersymmetric U(1) gauge theory follows. The results which we obtained are valid at tree level or equivalently at the first order in the nonanticommutativity parameter C_{\mu\nu}.Comment: 12 pages, some comments and references are added.

Life-Threatening Hematoma in Implant Surgery: A Case Report and Review Of The Literature

Dental implantlar günümüzde dişsiz çenelerde sıklıkla ve başarılı bir şekilde uygulanan güncel bir tedavi yöntemidir. Maksillo-mandibular alanlarda uygulanan bu tedavi yöntemi özellikle antikoagülan ilaç kullanımı olan hastalarda ciddi komplikasyonların meydana gelmesine sebep olabilir. Bu komplikasyonların en önemlisi majör cerrahi işlemler sırasında veya sonrasında görülen hayatı tehdit eden kanamadır. Bu tip kanamalar sonrasında ağız tabanı ve çevresinde hematom gelişmesi ile hava yolunun tam veya kısmi olarak tıkanmasına kadar giden ciddi problemlere yol açabilir. Sonuçta hastaların hava yolu güvenliğinin sağlanması için acil olarak entübe edilmesi ya da trakeotomi yapılması gerekmektedir. Bu vaka raporunda, 65 yaşında kalp kapak replasmanı nedeniyle varfarin sodyum kullanan erkek hasta protetik tedavi için kliniğimize başvurdu. Lokal anestezi altında çoklu diş çekimlerini takiben maksilla ve mandibulaya 9 adet implant yerleştirildi. Cerrahi işlemden bir gün sonra görülen yaygın ve diffüz tipte hematom yaklaşık on gün sürdü. Hastanın kan hemoglobin değerindeki ani düşüş nedeniyle iki defa acil kan replasmanı yapıldı. Kanama kontrolü için lokal hemostatik ajanlar ile bimanuel kompresyon ve elektrokoter kullanıldı. İyileşme tamamlandıktan dört ay sonra hastanın protezleri yapılarak tedavisi sorunsuz bitirildi

Modeling of convective drying kinetics of Pistachio kernels in a fixed bed drying system

Drying kinetics of Pistachio kernels (PKs) with initial moisture content of 32.4% (w.b) was investigated as a function of drying conditions in a fixed bed drying system. The drying experiments were carried out at different temperatures of drying air (40, 60 and 80°C) and air velocities (0.05, 0.075 and 0.1 m/s). Several experiments were performed in terms of mass of PKs (15g and 30g) using a constant air velocity of 0.075 m/s. The fit quality of models was evaluated using the determination coefficient (R2), sum square error (SSE) and root mean square error (RMSE). Among the selected models, the Midilli et al model was found to be the best models for describing the drying behavior of PKs. The activation energies were calculated as 29.2 kJ/mol and effective diffusivity values were calculated between 1.38 and 4.94x10-10 m2/s depending on air temperatures

An assessment of the relationship between peri-implant status and dental anxiety and oral health-related quality of life

Background: The purpose of this study is to evaluate the relationship between peri-implant diseases and dental anxiety and oral health-related quality of life. Methods: In a total of 101 subjects (44 females, 57 males, mean age 56.9 ± 12.1), 325 implants were examined using modified plaque index, modified sulcus bleeding index, probing depth, bleeding on probing, clinical attachment level, suppuration, and keratinized mucosa width. The Oral Health Impact Profile (OHIP- 14) was used to measure the impact of oral health-related quality of life. For the purpose of assessing the dental anxiety level, Corah’s Dental Anxiety Scale (DAS) was performed. In addition to dental implant measurements, the periodontal status of the participants' natural teeth was assessed by the Community Periodontal Index (CPI) of the World Health Organization. Results: All created groups as peri-implantitis, peri-implant mucositis, and peri-implant healthy were compatible with each other in terms of gender, age, income level, smoking status, and oral hygiene practices (p>0.05). A statistically significant correlation was found indicating that the peri-implant condition worsened as the education level decreased (p=0.033). There was no statistically significant difference between study groups in terms of DAS, OHIP-14, and CPI. There was a significant correlation between the scores of DAS and OHIP-14 (p<0.001). Conclusion: No relationship was found between peri-implant diseases and dental anxiety and quality of life. It was determined that as the anxiety levels of the participants increased, their quality of life decreased
